<h1>Windows Image Acquisition</h1>

<h2>SUMMARY</h2>

<p>This directory contains samples and test tools for Windows Image Acquisition
(WIA), a driver architecture and user interface for acquiring images from still
image devices such as scanners and digital still cameras. These samples will
not run on Windows 2000, Windows 98, or Windows 95.</p>

<h2>CONTENTS</h2>

<p>The following lists the WIA components and samples in the DDK:</p>

<h3>DOCUMENTATION</h3>

<p>Documentation on WIA can be found in the Platform SDK and this DDK. The DDK
contains information on developing drivers, and the Platform SDK contains
information for application writers. Note that WIA properties are only
documented in the Platform SDK under the topic Windows Image Acquisition/Wia
References/WIA Application Programming Interface/Constants/WIA Property
Constants.</p>

<p>Each sample directory contains brief documentation on how to build and run
that sample.</p>

<h3>FLAT-BED SCANNER SAMPLE DRIVER</h3>

<p>The Wiascanr directory contains a sample WIA minidriver for a flat-bed
scanner with a document feeder. See the documentation file Wiascanr.htm in the
Wiascanr directory for more information. (This sample replaces the old sample, Wiatscan.)</p>

<h3>SCANNER MICRODRIVER SAMPLE DRIVER</h3>

<p>The Microdrv directory contains a sample WIA microdriver for a scanner. A
microdriver is much easier to develop than a full WIA minidriver but provides
only basic functionality. See the documentation file Testmcro.htm in the
Microdrv directory for more information.</p>

<h3>DIGITAL STILL CAMERA SAMPLE DRIVER</h3>

<p>The Wiacam and Microcam directories contain a sample WIA driver for a
digital still camera and the Extend directory contains a sample user interface
extension. See the documentation file Wiacam.htm in the Wiacam directory,
Fakecam.htm in the Microcam directory, and Extend.htm in the Extend directory
for more information.</p>

<h3>TOOLS</h3>

<p>The Tools\Wia directory in the root directory of the DDK contains additional
tools to help with WIA driver development. Documentation for the tools is
contained in the DDK documentation.</p>

<h2>USING THE SAMPLES</h2>

<p>To quickly build and test all of the samples, run the <b style='mso-bidi-font-weight:
normal'>build</b> command in the src\wdm\wia directory by using the Free or
Checked DDK Build Environment. Next, run the &quot;copywia.cmd&#8221; batch
file to gather all of the binaries into a subdirectory named
&#8220;wiabins&#8221;. The camera and scanner samples can be installed in
Windows Me or Windows XP by using the <b style='mso-bidi-font-weight:normal'>Add
Device</b> icon in the Scanners and Cameras control panel. Use the <b
style='mso-bidi-font-weight:normal'>Have Disk</b> button to point to the
wiabins\drivers or wiabins\drivers folder. Wiatest.exe (from the DDK Tools\Wia
directory), MS Paint, the Scanner and Camera Wizard, or any TWAIN application
(through the WIA TWAIN compatibility layer) can be used to test the samples.</p>

<p>For more information on building and using the samples, see the individual
documentation files referenced earlier.</p>
